WARNING
Unexpected malfunctions of machines caused by radio devices/cell phones
Malfunctions are possible when radio devices or cell phones are used in the direct proximity of F-I/O. This can result in death,
serious injury or property damage.
If you scan the 2D matrix code/ID Link or use the "SIEMENS Industry Support App" with a powered-on F-I/O, then deactivate all
radio connections of the radio device/cell phone beforehand. Alternatively, power off the F-I/O before scanning.
